Abstract

In this study the lignin modified carbon paste electrode was applied for the electrochemical determination of dopamine, ascorbic acid and uric acid at pH 7.2 PBS solution with scan rate 50 mVs-1. The modified carbon paste electrode shows good electrochemical activity towards dopamine and ascorbic acid, where as in uric acid shows decrease in peak current when compared to bare carbon paste electrode. The effect of scan rate and concentration was studied at modified carbon paste electrode. The electrode process was found to adsorption and diffusion controlled and the detection limit was found to be 1.4 × 10-5 M.
